v MACHINE FOR TESTING THE ADJUSTMENT OF TYPE OF TYPE-WRITING MACHINES.

To all whom it may concern.

Be it known that I, FRANK E. Born, a

'citizenof the United States of America, re-

siding in Hartford, in the county of Hartford and State of Connecticut, have invented a certain new and usefulMachine for Testby resoldering. This, of course, necessitates considerable; handling of the mechanismby the testing operator and tolavoid this and otherwise facilitate such testin and adjusting is the object of this invention. With this object in view a special testing machine is provided which in all essential respects is similar to the regular working machines. It is however provided with an auxiliary set of bars or fingers carried bya segment located. in the machine just below the regular type bar segment, said fin rs being connected to the key levers in en 'stantially the same manner as are the t ebars in the working machine. This auxi iary segment is secured tothe side frames of the machine, and the regular working segment,

"withthe type bars'connected thereto, is-secured in operative position by readily controlled means and heldin the testing machine in the same position relative to the platen, etc., that it will occupy in a workmg machine' There is-of course an auxiliary finger for each .type bar, located immediately below or behind the same but not normally connected thereto, the -arrangement belng such that the ends of the fingers engage the type bars andraise them into pi'mtmg positions as the key levers are ma- *mpulated "As illustrated in the accompanying drawings, the invention is shown applied to a machine of the Royal Standar- Speciflcation or Letters Patent.

Application filed November 27', 191li'. Serial I I0. 63,706.

Figure 1 is a central sectional view of the machine I i Fig. 2, a view of detached parts showing a .type thrown into printing position by an operating fin ger':

Fig. 3, a plan view of the auxiliary seg' ment and a working segment showing their relative positions: and

Fig. 4, a fi out. elevation of the same.

The testing; machine of this invention is similar in general construction to the regular Royal Standard machine, comprising key levers 5 iivoted at their rear ends to a bar 6 which is secured to the sides 57 of the main frame, front levers 8 having their pivotalconne ctions to a bar 9 alsosecured to the sides vertical links 10 connecting the front levors 8 to the key levers 5, horizontal links 141 extending rearwardly from the front leve rs, links or rods 12 connecting the links 11 t) the universal bar '13,- springs H on these 1 ods 12 attached to an adjustable spring frame 15, a type head rest 16, carriage support and shift frame 17, carriage 18, plai en 19 and platen feed mechanism2O. a

The new added devices adapting the machine for the purposes of thisinvention consist of a series of bars or fingers 21 pivoted at 22 to a segl .ient 23 and connected at 21 to thelinks 11. The segment; 23 has side wings or extensions 24 and is securely held be tween the sides 7 of the main frame by screws 25, as shown'at Fig. 4. It'is also provided with slots, for the auxiliary bars or fingers 21 and with a bearing rod for the fingers similar. in construction to the slots and bearin rods of the regular type bar segments. Iie radius of the pivotal connections of this segment 23 with the fingers, 21 is suflicien ;1y greater than-the radius of the pivotal cmnections 26 of the regular type bar segment 27, with its type bars 28,

to Permit segment 23 to surround segment 27, as clearly shown at Fig. 4,

Type bar segments are made interchange-i ablei each on: being provided {with a type plate by screws 30, and are also made up "with a complete set of type bars. These segments, so equipped, are adapted to beset and held in proper working position in e 29, wh:eh is secured to the segment actuating finger. The type bars 28 'are'not directly actuated by the key levers and are in no way connected to any working member of the testing machine, thus greatly simplifyii'ig the work of applying them to said machine. The fingers 21 are plain bars, that is they are without type,and are adapted, by their free ends striking the under side of the type .bars, to throw the t pe bars 28 into printing position toward t e laten 19 as the key levers are manipulate as shown at Fig. 2.

The type 33 are secured to the ends of the bars28, preferably by a soldering process, as closely as possible to correct impression osition; and, with the bars duly assembled 1n a segment 27 and with the segment secured in the testing machine, the adjustment :of the type is determined by operating said machine. The typethat are found out of alinement, or otherwise disarranged, are

marked or suitably indicated as a guide for the ty e attaching operator to reset ,such imper ectly disposed type, the segment with the type bars attached being detached from the testing machine for this purpose. With the type closely approximating correct printing positions on their respective type bars, the segment is placed in the working machine in which it will be permanently used andthe final close adjustment of the type is made in the usual manner.

I' claim:

1. A machine for testin the adjustment of type of typewriting mac ines comprising key levers and a platen and adapted to hold a set of unconnected type bars and provided with a series of devices connected to the key {)QVGIS for individually actuating the type ars.

2. A machine for testing the adjustment of typewriting machines, comprising key levers, a platen, a fixed type bar segment,

type bars carried by the segment, and a series of devices connected and operated by the key levers and each of which is adapted to engage and operate a type bar.

. 3. A 'machine for testing the adjustment of type of typewriting machines comprising key levers and a platen and adapted to hold a type bar segment to which is attached a set of unconnected type bars and provided with pivoted fingers connected to the key levers and arranged to throw the type bars into printing position when the key levers are manipulated.

4. A machine for testing the adjustment of type of typewriting machines comprising key levers, a segment, fingers pivoted at one end to these ent, connection between the key. levers an fingers, and a platen, in com bination with a detachable type bar segment and type bars'pivoted thereto, said type bars being in the range of movement of the fingers so as to be actuated thereby as the key levers are depressed.

5. A machine for testing the adjustment of type of typewriting machines comprising key levers, a segment, fingers pivoted at one end to the se ent, connection between the key levers an fingers, and a platen, in com .bination with a detachable type bar segment, having its axis common with the finger segment and type bars pivoted thereto, said type bars' being in radial lines with the fingers, substantially as described.

6. A machine for testing the adjustment of typewriting machines comprising key levers, a segment, fingers pivoted at one end to the segment, connections between the ke levers and fingers, and a platen, in combination with a detachable type bar segment and type bars pivoted thereto, the pivotal connection of the fingers with their segment being in front of the pivotal connections of the type bars with their segment, said type barsbeing in the range of movement of the fingers so as to be actuated thereby as the key levers are depressed.

In testimony whereof, I have hereunto subscribed my name.
